HEAD-REST FOR BEDS.

Specification of Letters Patent.

Patented April 20, 1909.

Application filed July 23, 1908. Serial No. 444,961.

To all whom it may concern:

Be it known that I, HERBERT Knv'rz, a citizen of the United States, residing at Sharpsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Headlrlests for Beds; and I do declare thefollowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same,

This invention relates to improvements in head-rests for beds, couches, and the like.

The object of the invention is to provide a head-rest adapted to be adjustably connected to the head of a bed or couch and having means whereby the same may be raised or lowered to various elevations to support the occupant of the bed at any desired inclination.

WVith this and other objects in View, the invention consists of certain novel features of construction, combination and arrangement of parts as will be described and particularly pointed out in the appended claims.

In the accompanying drawing, Figure 1 is a side view of a portion of the bed, showing the application of the invention thereto, the head-rest being shown in a raised or operative position; Fig. 2 is a longitudinal sectional view through the bed, the head-rest and its operating mechanism, showing the rest in a lowered or inoperative position; Fig. 3 is a horizontal sectional view on the line 83 of Fig. 2 Fig. 4 is a detail horizontal sectional view on the line 44 of Fig. 2; Fig. 5 is a vertical longitudinal sectional view of a portion of the bed showing a modified construction of the invention; and Fig. 6 is a plan view of the same, partly broken away and in section.

Referring more particularly to the drawings, 1 denotes the head-rest which consists of a rectangular frame, 2, open at its lower end and having its side bars pivotally connected at their lower ends to the side rails of the bed. The frame, 2, may be covered with any suitable fabric, but is here shown as provided with a wire netting body portion, 3, the lower end of which projects through the mattress or springs of the bed and has an ranged therein a retaining rod, 4,

Pivotally connected to the side bars of the frame, 2, are depending operating levers, 5, which are pivotally connected together at their lower ends by a transversely disposed rod or bar, 6, to which is connected the branched lower end of an operating rope or cable, 7, the opposite end of which is con nected to a winding pulley, 8. The end of the rope, 7, is preferably secured to the pulley by passing the same through a notch, 9, formed in the periphery of one side of the pulley, and then lacing the end of the rope through apertures, 10, formed in said flange of the pulley. The pulley, 8, is mounted on a shaft, 12, which is revolubly mounted in a suitable bearing bracket, 13, secured to a frame, 1 1, fastened to the head of the bed stead, The pulley, 8, is preferably secured to the shaft, 12, by means of lugs, 12, formed on the opposite sides of the shaft and adapted to engage a notched hub, 8, formed on the pulley, as clearly shown in Fig. 4 cf the drawings. The bracket, 13, is provided with guard fingers, 15, arranged adjacent to the periphery of the pulley wheel, whereby the rope is guided and properly wound upon the ulley,

Fixedly mounted on the shaft, 12, is a worm gear, 16, with which is engaged a worm, 17, on a horizontal, transversely-disposed operating shaft, 18, which is revolubly mounted in the frame, 14, and extends to one side of the bed, where it is supported in a suitable bracket, 18, secured to the adja cent head post of the bedstead. The outer end of the shaft, 18, is provided with a crank handle, or other suitable operating device, 19, whereby when the shaft, 18, is revolved, motion will be imparted through the gears, 16 and 17, to the shaft, 12, and pulley, 8, to wind and unwind the rope or cable 7. If desired, the shaft, 18, may have fixedly mounted thereon near its outer end a sprocket wheel, 20, which is operatively connected by a sprocket chain, 20, to a' sprocket wheel, 21, mounted on a stub shaft secured to one of the side rails of the bed, within reach of the occupant of the bed. A crank handle, 21, is secured to the sprocket wheel whereby the same may be turned by the occupant of the bed and motion thus imparted to the operating shaft, thereby providing for the raising or lowering of the head rest by the occupant of the bed.

In Figs. 5 and 6 of the drawings is shown a slightly modified arrangement of the operating parts of the rest, said parts being shown in these figures as consisting of a threaded. operating rod, 22, the upper end of which is swiveled in a suitable bearing bracket, 23, and said end provided with a crank handle, 24:, which projects beyond. the head of the bed as shown. gaged with the rod, 22, is an adjusting sleeve,25 to which is connected one end of a pair of operating rods, 26, the opposite ends of which are connected to the lower ends of the levers, 5, and cross bar, 6, whereby when said threaded rod, 22, is revolved in one direction or the other, the sleeve, 25, will be moved up or down, thereby raising and lowering the head-rest. On the lower end of the rod, 22, is arranged a stop nut, 27, which is adapted to prevent the sleeve, 25, from being screwed entirely off the operating rod.

From the foregoing description, taken in connection with the accompanying drawing, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters-Patent, 1s:

1. In a bed, couch or the like, a head-rest, K

Operatively enshaft, a sprocket gear mounted within convenient reach of the occupant of the bed, an operating handle on said gear, a sprocket gear on said operating shaft, and a sprocket chain connecting said sprocket wheels, whereby said shaft is operated and the headrest raised and lowered by the occupant of the bed.

2. In a bed or couch, a head rest hingedly connected thereto, a raising and lowering mechanism, a sprocket gear arranged within convenient reach of the occupant of the bed, a sprocket chain to connect said gear with said raising and lowering mechanism, and a handle on said gear whereby the same may be operated by the occupant of the bed.

3. In a bed, an adjustable head-rest, an operating shaft projecting from one side of the bed, a crank handle on one end of said shaft, a worm on the opposite end thereof, a winding shaft, a worm gear on said shaft engaged by the worm on said winding shaft, an operating cable connected to said winding shaft, and means whereby said raising and lowering mechanism is operated by the occupant of the bed.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

HERBERT KINTZ.
